Title: Improvements in rolling mills
IPC: B21B37/50
Filed: 1929-05-10
Abstract: 312,066. Michel, L. R. May 19, 1928, [Convention date]. Rolling.-Continuous mills for wire strip &c. have the speed of one or more stands of rolls controlled by variation in the size of the loop of material between two stands. The rolled product 8 passes from the stand 1 over a roller 10, under a roller 9 and over a roller 11 to the stand 2. The roller 9 has a swivel mounting on a lever 13 pivoted at 14 and connected at 25 to a screw motor, and at 15 to a lever 16 having a weight 18 adjustable from a handle 19 by the chains shown. A pointer 23 indicates the tension in the rolled product. When the loop lengthens the screw motor is actuated to alter the ratio of expanding belt pulleys through which drive is transmitted to the stand 1 in order to reduce the speed of this stand. The lever 13 is linked to a pulley supported in the loop of a belt 34 connected to a counterweighted barrel 35 carrying a brake drum 36. As long as the product 8 is engaged by both stands the roller 10 is kept on its seating and by the connection shown in Fig. 4 the brake is maintained free When the end of the product leaves the stand 1 the roller 10 rises under the influence of the weight 41 and the brake is applied to the drum 36 and the belt 34 then sustains the lever 13, preventing the roller 9 from falling. More than two stands of rolls may be controlled by successive loops. Roll adjustments.-In a modification in which the control is effected by varying the pass in the stand 1, the rod 25 actuates a reversing switch for a motor geared to the pass adjusting mechanism.

Abstract: 1,065,213. Electrical voting apparatus; counters. A. VAGNARELLI. April 9, 1964 [April 10, 1963], No. 14740/64. Headings G4D and G4T. In a voting apparatus, a plurality of first counters 0, 1 ... n, connected in parallel, are each operated by a push-button P0, P1... Pn which also operates a common indicator lamp S to show that voting has occurred. The operating current causes a voltage drop across resistor r2 sufficient to release relay R and thereby interrupt the supply at contact C. Also, if more than one push button, P0, P1 &c., is operated simultaneously, a current-limiting resistor rl prevents operation of the counters and again the relay R is released. The circuit can be reset by depressing a push-switch PB to re-energize relay R. Another set of first counters 0a, la . . . na operated by pushbuttons POa,Pla . . . Pna, are each connected in series with a second set of counters laa, lab ... 1an, naa, nab . . . nan. Operation of pushbutton Pla, for example, operates counter 1a and also energizes relay R1a to close contacts lacl, 1ac2 so that one of the counters laa, 1ab ... 1an may be operated by one of pushbuttons Tlaa, Tlab . . . Tlan which also energizes relay laBl to open bar contact b1a and hence prevent more than one vote being recorded. Contact b1a is retained open by relay 1aB2 closing contact 1aC3. The circuits are reset by operating linked push-buttons PB, PBa and PBb. In order to set the second set of counters for operation without use of one of push-buttons P1a . . . Pna, commutator D moves switches D1a . . . Dna, D3, D4 to the I position and hence operates relays R1a . Rna. To meet the possibility of electricity failure, batteries are buffer connected to the mains supply. The electric equipment is housed in a metal hood, the front being antimagnetic and provided with the push-buttons. The inside of the hood is accessible through a rear shutter which is closed with a tight seal.

Title: Improvements in and relating to sheet delivery apparatus for use on printing machines
IPC: B65H29/16
Filed: 1931-05-22
Abstract: 378,965. Sheet delivery apparatus for printing-machines. MYERS, P., Lower Grattan Road, Bradford, Yorkshire. May 22, 1931, No. 15116. [Class 100 (i).] Sheet-delivery apparatus, particularly for a stop-cylinder printing-machine O, comprises revolving grippers A which deposit the sheets printed side up on a conveyer T, the tapes or the like of which are wound at one end around a stationary roller V<1>, and at the other end around a reciprocating roller V<2>, the speed of the tapes being controlled by rotating the rollers V<1>, V2 by means of a belt wound around pulleys on the rollers in the reverse direction to the tapes and passing over a pulley P oscillated at intervals to give the required motion to the tapes. As the grippers A lift the sheet from the machine O, the roller V<2> starts to move away from the roller V<1> and the pulley P is stationary so that the tapes T are unwound from the roller V<2>. When the sheet is supported by the tapes T, the grippers A release the sheet and at the same time the pulley P is driven slowly in a clockwise direction so that the sheet is carried forward by the tapes. Near the end of the forward movement of the roller V<2>, the pulley P is given a rapid clockwise rotation so as to transfer the sheet partly to a reciprocating carriage C of the type comprising endless-bands actuated by a pawl D<1> engaging a chain D so as to carry the sheets over a pile table and deposit them thereon. The clockwise rotation of the pulley P continues during the initial part of the backward movement of the roller V<2> so as to ensure that the sheet passes completely on to the conveyer C and so as to allow the grippers A to pass between the conveyers C, T ready to deliver the next sheet. Subsequently, the cycle of operations is completed by giving a rapid anticlockwise rotation to the pulley P so as to rewind the tapes T from the roller V<2> to the V<1>, so that the tape conveyer is ready for the succeeding sheet. The pulley P is given its movements by a rack-and-pinion gearing R, R<1> operated from a cam-and-lever mechanism driven from a shaft G which also reciprocates the carriage C and roller V<2> through suitable mechanism. The carriage C may be omitted in small machines.

Abstract: 489,317. Valves; clutches. KEGRESSE, A. June 1, 1937, No. 15261. Convention date, June 6, 1936. [Class 135] [Also in Group XXIV] A device for automatically controlling the supply of working fluid in rotating hydraulic systems, and in particular change-speed gears for motor vehicles embodying multiple hydraulically-operated clutches, comprises the combination on a rotating member 1 of one or more radially disposed valves 9 opening under the pressure of the fluid against a spring 14 arranged in series with a radially disposed centrifugally-actuated valve 3, having a circular seat and a balancing piston portion 5, which is urged into the closed position by a spring 7 regulated to overcome the action of the centrifugal force when the speed of the member 1 falls below a certain speed to interrupt the passage of the working fluid through passages 2, 8 and valve 9. Thus in' automatically operated change-speed gear systems which utilize the pressure of fluid delivered by an engine-driven pump, which pressure may vary according to different conditions of temperature of the engine as well as to the speed, a positive disengagement of all the speeds can be obtained at a certain predetermined value of the engine speed irrespective of the conditions of temperature of the engine, since the valve 3 is balanced for pressure and is dependent for operation on the speed alone. Specification 466,543, [Group XXIV], is referred to.
